public final class MockAnalyzer
Analyzer for testing
This analyzer is a replacement for Whitespace/Simple/KeywordAnalyzers for unit tests. If you are testing a custom component such as a queryparser or analyzer-wrapper that consumes analysis streams, its a great idea to test it with this analyzer instead. MockAnalyzer has the following behavior:
MockTokenizer
are turned on for extra
checks that the consumer is consuming properly. These checks can be disabled
with setEnableChecks(boolean)
.
